Feb 24, 2010 · to define salt-water solution, You need to select fluid species Water [H2O(l)]. Then, you need to create pseudo species named Salt, with similar properties. Then, you need to create pseudo species named Salt, with similar properties.
Jul 20, 2018 · I wrote an UDF using the DEFINE_CG_MOTION macro. The problem I have is that it executes at every iteration and I only need it to execute at the end of every time step. I found the macro DEFINE_EXECUTE_AT_END which does what I want to but I can't make it work with the other macro. I tried: DEFINE_EXECUTE_AT_END(exec_end) {DEFINE_CG_MOTION ...
Dec 14, 2009 · To define Moist Air in Fluent JW: FLUENT: 1: April 15, 2006 17:31: Mixture model in FLUENT 6.0 Siva: FLUENT: 0: March 24, 2004 03:39: All times are ...
Jul 13, 2005 · You can use the custom field funtion capbility in FLUENT. First you define the second-invariant of deformation tensor with First you define the second-invariant of deformation tensor with Q = 0.5(W*W - S*S) where W is the vorticity magnitude (you can find it under the "Velocity" menu) and S is the mean rate-of-strain (you can find it under "Derivatives" menu).
Nov 25, 2015 · Single Phase Flow), you'll find the transport equations Fluent will use to handle this UDS. As you can see from the equations it tried to make the scalar itself dimensionless. This means that the diffusion coefficient used is multiplied by the density (so if you specify the diffusion coefficient of salt in fluent you will have to multiply by the density, otherwise you'll be 1000x too low).

Jun 2, 2020 · I'm doing a fluid-solid coupling heat transfer problem. Since I've just started using Fluent, I've created a very simple test case (no radiation) to figure out what Fluent can do (attachement): 1.png Based on the description of udf DEFINE_HEAT_FLUX, it modifies the diffusive heat flux coefficients using equation:
Aug 2, 2007 · Use the Species model and define the properties of the "mixture species" in the materials window to have H2O and Air (H2O must be the top one). Choose "volume-wheighted" for density and "mass-weighted" for thermal conductivity and viscousity. Then specify the moisture mass fraction for inlets to the domain (this is the humidity ratio in the ...
Sep 8, 2006 · FLUENT will automatically include the terms needed to model mass transfer in all relevant conservation equations. Another option to model mass transfer between phases is through the use of user-defined sources and their inclusion in the relevant conservation equations. This approach is a more involved but more powerful, allowing you to split the source terms according to a model of your choice.
Apr 25, 2009 · If you have two volumes, that are simply attached to each other, and you define (one) interface at interior (or whatever else) Fluent will create a wall for that other interface!! You can assure that by using in the face command field the "connect faces" button (looks like a plug). Select (all) faces of your domain and connect. That will cause ...
